8.75 Not centered?!?!

Not a surprise that the axle isn't centered up perfect in the car. These cars were built with sloppy tolerances all around.

Now it's time to massage stuff to get it spot on. Verify the perch locations.
Perches are supposed to be equal distance from the housing ends correct? Dr. Diff informs 42" apart using his offset front hangers. In the pics, it's 41.5". Will see when I get the hangers & it's bolted up tight. Just trying to get as much info as possible before perches are welded. Thank you.
